√  Integrated with calibrator, load box, regulator, easy to connection.
√  Secondary current to be switched by rotary.
√  External regulator and current injection could be connected to increase or adjust capacity easily.
√  Protective circuit, reliable and safe.
√  Under CT/PT measuring, the impedance of secondary circuit or the active component and idle component of admittance could be measured at any time.
√  Polarity could be indicated automatically, and auto break differential current/voltage circuit to insure the safety and alarming by sound light.
√  To be used as rectangular coordinate system AC potentiometer, to measure the AC low current or low voltage.
√  To be used with isolating PT and control unit to measure the secondary drop voltage of PT.
√  The reference CT/PT or two stage CT/PT or Inductive Divider all could be used as standard reference during measuring.
√  LCD screen, English interface.
√  40 groups CT storage, the 1% error results also can be stored.
√  PC and corresponding software could be connected to operate.
√  Build-in printer.
